TIMOTHY ROGERS, OF SPRINGFIELD, OHIO, ASSIGNOR, BY MESNE ASSIGN MENTS, TO THE ROGERS FENCE COMPANY, OF SAME PLACE.

LAWN-MOWER.

SPECIFICATION forming part of Letters Patent No. 333,549, dated January 5, 1886.

Application filed August 6, 1884. Serial No. 139,801. (No model.)

.To all whom it may concern.-

Be it known that I, TIMOTHY Roenns, a citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Lawn-Mowers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in lawn-mowers.

It applies to that class of lawn-mowers using rotary knives; and it consists in the construction of the frame and in the arrangement of the gearing and parts hereinafter described and claimed.

Figure 1 is a side elevation of alawn-mower (with one ground-wheel removed) having my improvements embodied therein. Fig. 2 is a section of the same through line as with the ground-wheel replaced. Fig. 3 is an inside view of one of the ground-wheels. Fig. 4 is a perspective view of the frame and gear-oases as cast in one piece.

A is the frame, which is of substantially rectangular form, its side bars turning downward just forward of the wheel-centers at right angles, forming hangers f, which are connected at their lower ends by the cutterbar piece d. On the outside of side bars, (1, are attached the ellipse-shaped gear-cases G, with their longer axes in line with the framebars d. In the middle of the rear bar is an extension for the ton gue-bar,with a recess, d", therein to receive the latter when attached. The whole frame with the attachments described is cast in a single piece.

Ground-wheels B B are concave, havean internal hub, pawls loosely pivoted in the same which engagethe teeth of the internal ratchetwheel, a, in spur-wheel a. This latter is the driving spur-wheel and engages a pinion rigidly attached to a spur-wheel of the same size as the driver a, which latter spur-wheel in turn engages another pinion rigidly attached to the knife-reel shaft under the first spur or drive wheel. The train of gears thus alternate with each other in their arrangement, and being confined to a small space the machine is light, compact, and strong, and has the advantage of being easily handled and operated.

The hollow ellipse-shaped gear-case G (seen in Figs. 2 and 4.) extends out far enough to cover and protect the gear within the cavity nected by the cutter-bar d, which supports the fixed blade E. The main shaft D has the knife reel a secured thereto and extends through the frame near its forward angle and through the inner wall of the case on either side of the machine. attached to this shaft just outside of the wall of case 0, and outside of this pinion on the shaft D is the driver spur-wheel a with its internal ratchet, (1, within which the hub or collar z in the ground-wheel extends. gravity-pawls d in recesses in the periphery of hub i engage the teeth of ratchet-wheel a in the spur-wheel a, which latter engaging pinion b, pivoted on stud e,drives this and the spur-wheel b, which is in one piece with it, 80

and the latter engaging the fixed pinion b on the reel-shaft (inside or" spur-wheel a) drives the knife-reel with increased velocity. The rims of the ground-wheels extend over the ellipse-shaped gear-case O, as seen in Fig. 2. 85

The hubs of these wheels are extended outwardly to give along and firm bearing. The groundwheels make about one revolution to four of the knife-reel, the increase being due to the train of multiplying-gearing described. The 0 knife-reel shaft being central with the groundwheels has both the driving and the driven gear thereon and forms the axle of the machine also.

The construction of the gravity-pawls and 5 The pinion b is rigidly The having an extension at the middle of the rear bar of the same provided with a recess, 01,

therein for the tongue, and being cast in a 15 single piece with the attachments described, for the purpose specified.

In testimony whereof I aflix my signature in presence of two witnesses.

TIMOTHY ROGERS.
